Power and Temperature
To test the power and temperature we perform a manual run-through in Cyberpunk 2077 at “Ultra” settings for real-world in-game data. We use GPU-Z sensor data to record the results. We report on the GPU-Z sensor data for “Board Power” and “GPU Chip Power” when available for our Wattage data. For temperature data, we report the GPU (Edge Temp of the GPU or Package Temp) as well as Hot Spot (Junction Temperature) when available for our temperature data.
The SAPPHIRE NITRO+ AMD Radeon RX 6750 XT had a GPU Chip power draw of 230W. When we overclocked it, that increased by 7W. Compared to the Radeon RX 6700 XT, at 230W GPU Chip Power, the 6750 XT consumes 23% more GPU Chip Power. Considering we only saw 5-10%, or 15% in one instance, performance improvement, that difference is not very power efficient. The power has increased more than the performance increase, so to get 10% more performance, requires 20%+ more power. This is also more power-hungry than the RTX 3060 Ti.
The SAPPHIRE NITRO+ AMD Radeon RX 6750 XT really shines in its cooler performance. The SAPPHIRE NITRO+ has a GPU temp of only 66c and Hot Spot at 91c. This is running cooler than even the Radeon RX 6700 XT, which has lower clock speeds, it’s at 76c GPU temp and 96c Hot Spot. The SAPPHIRE NITRO+ also runs cooler than the GeForce RTX 3060 Ti. It is in fact, the coolest running video card here in our lineup today. When we overclocked it we pushed the fans to 100% and overclocked it’s at a very cool 48c, can you believe that only 48c for that much power it is drawing. The SAPPHIRE TRI-X cooling configuration is very robust, and does the job greatly, providing phenomenal cooling.
